    @Nucleus Inc. NOC, generally, the issue when Plesk is unable to resolve domain names may have different causes.

    One of the causes is described in this article. The idea is that file with server DNS settings has the wrong permissions.

    In case permissions of /etc/resolv.conf on your server are correct, make sure that server network configuration is correct and there no issues on ISP side.
